Lots of cool and useful features they have thought about from the scale locked pitch bend, to the MPE upscaling to achieve polyphonic pitch bend of chords on traditional keyboards, to the features like "no last bend" and "no return bend".
It says it is compatible with Reason "Using MIDIMood’s Pluchain". I'm not sure how compatible it is though with lack of MPE support in Reason.
I prefer using my Seaboard Block for MPE stuff, but this seems very useful and I would totally use it with my traditional keyboards.
